I posted this on the other board, maybe that was the wrong place. Lets try here.
Does any one have any idea why the interior lights wont turn off. Lights go out when driving but no sooner than you stop, the lights come back on. It acts like it has a bad door switch but I can't seem to find it for the front door. Also the automatic door locks don't work, power locks will unlock but won't lock when you push the button. Unlock the door with the key fob, no horn chirp, no flashing lights

i had same problem after i put my keyless in my 99 ga. the problem with mine was a bad door switch. it sometimes would work or it wouldnt recignize the door being closed. all that i did was go around to all the doors and close them HARD. not to hard (do wanna break glass), but did that a few times to jossle the switches. it worked so far (about 4 months) and i havent had a prob since. it aint the best solution but it helps for the time being.

I agree that your first problem is likely the door ajar switch (or associated wiring) in one of the doors. The reason that the lights only turn on when you are not moving is because the module that controls the interior lights is designed to do this (turn off interior lights when vehicle is in motion).

To help isolate this a bit more....if you have driver door closed and stick key in ignition do you get key warning chime? If you have to open driver door to hear it then you know the problem IS NOT with driver door.

Then you will need to check the other doors individually.

Here are a few schematics

This one shows door ajar wiring (which is a connector that goes directly to the latch assembly

This one shows wiring on right side of IP. The stuff labelled "3" are the connectors for the Right IP fuse block (back side). On the front side which you can see when you pop off the fuse door you will see connector "C3" which contains the 3 circuits that go to all the passenger door ajar switches.

I don't know how much you know about electrical stuff but the first thing I would do would be pull off that connector and check cavities B11 and C11 for continuity to ground to further isolate which door ajar switch/wiring is causing problems.
